Fractions???

In this example, the best way is probably to change each into a decimal
1/2 = 0.5
1/3 = 0.333
22/63 = 0.349
18/33 = 0.545
19/81 = 0.235

Order then becomes (lesser to greater) :-
19 / 81 , 1 / 3 , 22 / 63 , 1 / 2 , 18 / 33

Just use your windows calculator and type in the fraction as it appears, which will give you the decimal for each fraction.... Example 1/2 = .50
1/3 = .33
22/63 = .349

You do the rest...... RF

Turn them into percents by dividing the numerator by the denominator.

lesser to greater
19/81, 1/3, 22/63, 1/2, 18,33

greater to lesser
18/33, 1/2, 22/63, 1/3, 19/81

Try to make the denominator the same then which ever numerator is higher is the bigger number

i.e. 1/2 and 1/3

1/2=3/6 1/3=2/6

3 is greater than 2 so 1/2>1/3

The same can be applied to all the other ones you posted
